Katie, I'm sure NO ONE is going to bash you or judge you in any way on the decision you have to make in regards to Abbie. It's bad enough what you must be going through taking in these kitties.
YOU are doing the RIGHT thing for Abbie and please, DO NOT feel guilty or even second guess your decision. From the sounds of it, it is the ONLY decision. If you hadn't taken in this sweet girl, she would surely die a cold lonely death. God will NOT punish you or judge you for doing the RIGHT thing. Of course you care about these babies, or else you wouldn't have taken them in.
Look what happened to our dear SweetPea. She lost 4 of her 5 babies and that was very hard on me to see and yes, I second guessed my decision.

Prayers and positive thoughts on the way for Abbie and the rest of the babies.

This tough time will end. Just know in your heart that you don't need to go it alone. We will always be here for you.
